OIL-GAS BURNER.

Specification of Letters Patent.

Patented Apr. 26, 1910.

Application filed November 17, 1909. Serial No. 528,460.

To all whom it may concern:

Be it known that I, CURTIS .G. LILLI- BRIDGE, a citizen of the UnitedStates, residing at Shattuek, in the county of Ellis and State ofOklahoma, have invented certain new and useful Improvements in Oil-GasBurners; and I do declare the following to be a full, clear and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in oil gas burners.

The object of the invention is to provide an improved construction ofburner having means whereby the oil when fed thereto will be evenlydistributed and thoroughly vaporized before being discharged into theair mixing compartment of the burner.

WVith the foregoing and other objects in View, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claims.

In the accompanying drawings, Figure 1 is a side View of a burnerconstructed in accordance with the invention; Fig. 2 is a horizontalsection on the line 22 of Fig. 1; Fig. 3 is a central vertical sectionon the line 3--3 of Fig. 2; Fig. 4: is a side view of the inner sectionof the burner; Fig. 5 is a horizontal section of a modified form of theburner.

As shown in the first four figures of the drawings, my improved burnercomprises a substantially conical-shaped hollow inner section 1 havingon its lower edge an annular radially projecting flange 2, and havingformed around its sides a series of vertically elongated openings 3between each of which is formed a vertically disposed groove 4:, theupper ends of which grooves communicate with flared passages 5 formedbetween a series of lugs or offsets 6 formed at the upper end of each ofthe openings 3 as shown. In the upper end of the section 1 is formed anoil receiving and distributing recess 7 Adapted to be engaged with theinner section 1 of the burner is an outer substantially conical-shapedhollow section 8 having in its upper end a threaded opening 9 in whichis screwed a bushing 10 whereby the oil supply pipe is connected to theburner. In the sides of the outer section 8 adjacent to its lower edgeare formed a series of vertically elongated openings 11 between each ofwhich on the inner surface of the section 8 is formed an inwardlyextending vertically disposed flange or rib 12. When the outer section 8is engaged with the inner section 1, the ribs 12 enter the grooves orchannels 4 while the lugs 6 engage the inner surface of the outersection 8. lVhen thus engaged, the lower edge of the section 8 restsupon the flange 2 on the lower edge of the section 1, thereby completelyinclosing the upper portion of said inner section with the openings 3and 11 registering. \Vhen the parts are thus arranged and oil isadmitted through the connection at the upper end of the outer section,the oil enters the depression 7 in the upper end of the inner sect-ionand overflows therefrom, thus evenly distributing the oil which runsdown the inclined sides of the upper portion of the inner section 1. andenters the flaring passages 5 and runs down the grooves or channels 1 onopposite sides of the ribs 12 and is vaporized by the heat of theburner. The vapor thus formed mixes with the air which passes outthrough the openings 3 from the interior of the inner section 1 andforms a combustible gas which burns freely through the openings 11 inthe burner sections.

My improved burner is adapted to be set into the fire box of any form ofstove and the oil is fed thereto by gravity or other means from asuitable oil supply tank not shown. WVhile the burner has been describedas being substantially conical in shape, it is obvious that the same maybe constructed in other shapes to facilitate the enga ement of the samewith differently shaped lire boxes, one modification in the form of theburner being shown in Fig. 5 of the drawings, whereby the same isconstructed in an elliptical shape in cross section, thus correspondingmore with the shape of a narrow or oblong fire box. The openings in theinner and outer sections of the burner are herein shown and described asbeing of elongated shape. It is obvious, however, that these openingsmay be of any desired shape or that instead of providing one elongatedopening, two or more openings may be arranged in the sides of thesections.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.

Having thus described my invention, what I claim is:

1. In an oil gas burner, an inner section having formed therein a seriesof openings, oil feeding grooves formed in the sides of said sectionbetween each of the openings therein, an outer hollow section adapted tobe engaged with said inner section, said outer section having formedtherein a series of openings adapted to coincide with the openings inthe inner section, and a series of ribs formed on the inner side of theouter section to engage the grooves or channels in the outer side of theinner section.

2. In a burner of the character described, an inner substantiallyconical shaped hollow section having formed therein a series ofopenings, an annular radially projecting flange on the lower edge ofsaid section, a series of radially projecting lugs formed on the outerside of said section above the openings therein, oil conducting groovesformed between said openings, flaring oil passages formed between saidlugs and communicating with said grooves, a conical shaped hollow outersection adapted to be engaged with said inner section, said outersection havlng formed therein a series of openings adapted to colncidewith the openlngs 1n the insane inner section, a series of radialvertically disposed ribs formed on the inner wall of the outer sectionand adapted to engage the grooves or channels in said inner section, andmeans whereby an oil supply pipe is connected to the upper end of saidouter section.

'3. In an oil gas burner, an inner substantially conical hollow sectionhaving formed therein a series of elongated openings and ings coincidingwith the openings in the inner section, a series of radial inwardlyprojecting ribs formed between said openings, and adapted to engage thegrooves and passages in said inner section, and means to connect an oilsupply pipe with the upper end of said outer section.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
